Silene uniflora - sea campion Sea campion can be considered the coastal equivalent of Bladder campion with its white flowers joined at their base to form a tube & surrounded by a bladder-like calyx. Indeed in some older books it is listed as a subspecies of Bladder campion (S. vulgaris ssp. maritima). However it differs in habit with its non-flowering shoots forming low cushions or mats with leaves that are waxy & sea green. There is usually only one flower per shoot & the petals are broader & less deeply notched. Flowers from May to July. NB previously known as Silene maritima. Sowing the seeds Tolerates most soils, prefers partial shade, Sowing time throughout the year, with best results sowing March/April & August to September. Sow direct in the flowering position Prepare the soil by lightly scarifying to create a shallow broken surface. Thanks for looking. Sea Campion - Silene Uniflora Approx. 100 Seeds Wild Flower Seeds
